Searching for codeblocks and blockquotes

It is no big deal, but it would be nice to be able to search for messages with codeblocks (`this` and ```this```) and blockquotes (> this) in the same way that you can search for messages with videos, images, etc. using the has: parameter. Potentially "has:code" and "has:quote" or something.

There is a related suggestion at https://support.discord.com/hc/en-us/community/posts/360051620094 which brings up searching for codeblocks; I believe it would also be good to have blockquotes be searchable.
